Hi all, I was wondering if there was a way to tell if an instance of Oracle on a system has a database installed or not?

Has anyone tackled this problem before? ...

I just don't get it. I use cocos2d for development of a small game on the iPhone/Pod. The framework is just great, but I fail at touch detection. I read that you just need to overwrite the proper functions (e.g. "touchesBegan" ) in the implementation of a class wich subclasses CocosNode. But it doesn't work. What could I do wrong? the f...
The question I meant to ask concerned the mantissa, not the exponent, and has lots to do with the question I asked earlier in the week regarding "missing" digits on the sum of two negative floats. Given that the mantissa has a variable precision, how does one tell if one has overflowed the mantissa's current precision setting? Or, from ...

Anyone have any ideas on how to test for something specific for IE6 (and not IE7) using jquery.support? My problem is that IE6 supports :hover psuedo-class only for anchor elements and IE7 does support it for all elements (as FF, Chrome, etc). So I want to do something special in case the browser does not support :hover for all elements...
I'm looking for the best (possible on most PHP 5.2 installs and still actively developed) way to detect a files MIME type in PHP.

Is there a simple and automatic way of checking if a visitor to my website (written in asp.net) is using the latest version of his browser? This would allow me to display a message to inform them that they're running an old version and that they might want to upgrade.

I am coding up a program for automated testing which randomly clicks an open application window using various User32.dll library calls. My current problem is this, if a click would open a dialog, using Process.WaitForInputIdle() does not wait long enough for that dialog to be detected the next trip around the loop, which means several cl...
In a Linux environment, I need to detect the physical connected or disconnected state of an RJ45 connector to its socket. Preferably using BASH scripting only. The following solutions which have been proposed on other sites do NOT work for this purpose: Using 'ifconfig' - since a network cable may be connected but the network not pro...
I'm writing a PHP script that converts uploaded video files to FLV on the fly, but I only want it to run that part of the script if the user has FFMPEG installed on the server. Would there be a way to detect this ahead of time? Could I perhaps run an FFMPEG command and test whether it comes back "command not found?" ...

Is there an easy way to scan through your sources and tag all functions which can potentially throw exceptions? Does the build in visual assist have some hidden option to colour these functions in a spec...
